  The 
  descriptions, 
  generic 
  and 
  specific 
  in 
  this 
  paper, 
  " 
  Diagnoses 
  of 
  new 
  Genera 
  

   and 
  Species 
  of 
  Deep-sea 
  Fish-like 
  vertebrates," 
  are 
  among 
  the 
  most 
  brief 
  and 
  unsatis- 
  

   factory 
  in 
  our 
  ichthyological 
  literature. 
  This 
  paper, 
  by 
  a 
  most 
  able 
  and 
  competent 
  

   ichthyologist, 
  from 
  the 
  brief 
  and 
  superficial 
  character 
  of 
  its 
  descriptions, 
  is 
  likely 
  to 
  

   cause 
  great 
  confusion 
  in 
  the 
  study 
  of 
  the 
  Bassalian 
  fauna 
  of 
  the 
  Atlantic, 
  unless 
  soon 
  

   followed 
  by 
  accurate 
  and 
  sufficient 
  descriptions.
